Abstract
The present disclosure provides a methodology that incorporates real-time measurement of conductor temperatures and ground clearances using a transmission line monitor, coupled with information technology and data analytics, to allow utility operators to manage their transmission systems using a dynamic line rating process. Dynamic line ratings may incorporate real-time or near-real-time data of transmission line conditions in lieu of conservative assumptions, in order to more accurately assess actual transmission line performance such that more of the power conveying capacity of the existing transmission infrastructure can be accessed with continued compliance with safety requirements applicable to the transmission line system.
Claims20
An apparatus for determining a current rating for an electrical transmission line, comprising:
- a receiver configured to receive line clearance measurements and line temperature measurements from a transmission line;
- and
- a processor coupled with the receiver and configured to calculate a dynamic ampacity for the transmission line based at least in part on the line clearance, line temperature, and conductor characteristics of one or more conductors of the transmission line.
